DIY Guyatone Dual Octave, 1 or 2 octave down monophonic square wave pedal with an added clean boost for increased level output. 1 or 2 octave selection footswitch allows for switching between octaves on the fly.
Clean and octave blend controls allow for precise effect blending, players that use the MXR Blue Box will find this pedal familiar but will experience better note tracking and more tweakable options with a higher output volume.
This project is designed to fit a 1590BB2 enclosure. Sale is for the PCB only, all other parts not included.
PCB Dimensions - 100mm x 40mm
